Define your data as a "grouped.data" object using the function of the  
same name in package actuar. Then you can simply use hist() as usual  
to get what you want. See:

@Article{Rnews:Goulet+Pigeon:2008,
  author = {Vincent Goulet and Mathieu Pigeon},
  title = {Statistical Modeling of Loss Distributions Using actuar},
  journal = {R News},
  year = 2008,
  volume = 8,
  number = 1,
  pages = {34--40},
  month = {May},
  url = http, pdf = Rnews2008-1 }
